Brand New Mercury Reman 300XS (just out of break-in) surging/skipping on the top end.
No Alarms.The powerhead was replaced due to an oil leak.
The WOT RPM's hit a wall at 5400 RPM, when the boat setup used to turn +6000 RPM. I took a quick look at the plugs late last night and they all appeared dry and normal. Next on the list is fuel pressure tests.
I'm leaning more towards a fuel issue because surge/skip can't be felt at slower cruising RPM's, but i'm no locked in on that theory.
My list of possibilities not in any order:
TPS
MAP
Compressor reeds
Fuel pump(s)
Coil
Spark plugs
???
Can't lake test again till Friday to get on the water fuel pressure tests, so I'm seeking out other items to check while its sitting inside my shop.
